Sashas the only one not going to the dance so wwe booking logic dictates it makes the most sense for her to eat the pin. Likely with a bayley mistake to "further the split."I'm not sure what Tamina would gain from beating Sasha again she already did it two weeks ago wouldn't it make more sense for her to pin Bayley? that would actually make her a bigger threat. not beating someone who she already won against very recently.
Then again that might be too logical for WWE.
